The Ivorian claimed the Marc-Vivien Foe accolade after finishing ahead of Algeria and Montpellier's Ryad Boudebouz and Cameroon's Nations Cup winning captain Benjamin Moukandjo of FC Lorient.
Reports indicate that the annual award is named in honour of Cameroon international Foe who passed away after collapsing on the pitch in 2003.
Meanwhile, Seri is the second Ivorian to win the accolade after Gervinho won it on two consecutive occasions, in 2010 and 2011.
Having played 13 times for the Elephants thus far, Seri has been influential for the French giants this season netting six goals and providing nine assists to help them to a third-place in the league.
The former ASEC Mimosas player went on to have stints with Portuguese side FC Porto and Paços de Ferreira respectively before joining Nice in June 2015.
Having made his international debut against Sierra Leone in September 2005, he played for Ivory Coast at the 2017 CAF African Cup of Nations in Gabon as they suffered an embarrassing group stage exit.
